HEATING OR COOLING APPARATUS.

Specification of Letters Patent.

' Application filed December 26, 1917. Serial No. 208,854.

a variable numberof elements arranged horizontally and each composed ofdouble walled tubes or rings, varying in diameter and length accordingto the size of the apparatus. These elements are"connected togetheralternately at their right and left cm s by means of conduits to allowthe circulation of the heating or cooling fluid between the walls, thefluid being fed and exhausted through common feed and exhaust pipes.

The annexed drawings illustrate the invention.

Figure 1 is a front View of the heating or cooling apparatus composed ofa certain number of horizontal elements arranged in vertical rows.

Fig. 2 is a side view of Fig. 1.

Fig. 3 is a perspective View of a vertical row of elements. V

Fig. 4 is a vertical section of an element drawn to an enlarged scale.

Fig. 5 is a section on line AA of Fig. 4.

As shown more particularly by Figs. 4 and 5, each element a is composedof'two concentric metal rings Z), 0 connected at their ends by bendingdown the edges of the outer ring on to the periphery of the inner ring,said ends being joined together by soldering. In the annular spacebetween the two rings the water Or steam serving for heating or the airor liquid used for cooling'circulates the heating or coollng fluidarriving through the pipe d through the tube 0 and being exhausted intothe outlet pipe by means of the tube V These elements are arranged at ashort distance from each other and are connected to gether by the tubesg and the ties h.

The elements are constructed of sheet metal, galvanized or leaded, ofcopper. brass, aluminium, etc, the connecting tubes beingof similarmetal. 7

It can be seen that the apparatus is composed of a variable number ofhorizontal elements, arranged one above the other and in. one or morevertical rows shown by Fig. 1. It can be screened and surrounded by anyperforated covering metal or otherwise. Y

The 'apl'iaratus is suitable for water or steam heating for dwellings,public buildings,workshops, factories, ships, etc, or as a heatingdevice for forcing-houses, drying kilns and drying rooms, or for itsapplication to cooling.

\Vhat I claim as my invention and desire to secure by Letters Patent ofthe United States is 2- A heating or cooling apparatus comprising incombination a number of series of superposed horizontal elements, eachCOlIlposed of relatively short concentric tubes between which is arelativley thin space through which the heating or cooling fluid flows,vertical fluid conveying tubes connect- .ing alternate ends of theelements of a series so that the fluid flows in contrary directions Ithrough successive elements of a series and inlet and outlet pipes forconveying the fluid to and from the series of elements.

In witness whereof I have signed this specification in the presence oftwo witnesses.
